Thermodynamics and the quantum speed limit in the non-Markovian regime
Arpan Das, Anindita Bera, Sagnik Chakraborty +1
Quantum speed limit (QSL) for open quantum systems in the non-Markovian regime is analyzed. We provide a the lower bound for the time required to transform an initial state to a fi…
A quantum enhanced finite-time Otto cycle
Arpan Das, Victor Mukherjee
We use fast periodic control to realize finite-time Otto cycles exhibiting quantum advantage. Such periodic modulation of the working medium - bath interaction Hamiltonian during t…
Resource state structure for controlled quantum key distribution
Arpan Das, Sumit Nandi, Sk Sazim +1
Quantum entanglement plays a pivotal role in many communication protocols, like secret sharing and quantum cryptography. We consider a scenario where more than two parties are invo…
Two-qubit mixed states and teleportation fidelity: Purity, concurrence, and beyond
Sumit Nandi, Chandan Datta, Arpan Das +1
To explore the properties of a two-qubit mixed state, we consider quantum teleportation. The fidelity of a teleported state depends on the resource state purity and entanglement, a…
Measurement Based Quantum Heat Engine with Coupled Working Medium
Arpan Das, Sibasish Ghosh
We consider measurement based single temperature quantum heat engine without feedback control, introduced recently by Yi, Talkner and Kim [Phys. Rev. E 96, 022108 (2017)]. Taking t…
